After you go through the Stilled Eldin Volcano, you find an entrance into Eldin Temple.

Find a Waypoint

Check on the waypoint to add it to your map. You can stand in the hot springs in this room to restore health. Go through the north door when you're ready.

Get a Small Key

There are two Fire Keese here. Go through the north door. There are two dark Zirros. Throw their bombs to break the northeast block (or create a Zirro echo or Bombfish echo of your own), then pull up the treasure chest and open it to get 8 twisted pumpkins.

Go south to the previous room and go through the east door. Bind to the lava rock and move it onto the shorter lava spout. Wait for the lava spout to go back down, then jump onto the lava rock, and jump from there to the ledge to the east. Then create a lava rock on the taller spout and ride it up to the higher ledge. Go through the north door.

Create a flying monster echo but don't try to fly straight to the treasure chest in the northeast corner. The air vents don't send you far up enough. Instead, float west, then go north and use that air vent to go to the air vent to the east, and use that one to go to the air vent east of that. Then float to the treasure chest and open it to get a Small Key.

Get a Second Small Key

Use a flying monster echo to float south, and go through the door. Then go west and go through the door so you're back in the room with the two Fire Keese and the locked door. Unlock the west door and go through.

The lava in this room goes up and down. There is a treasure chest near the southwest corner of the room. Bind to it and pull it up. The lava will probably start going back up before you have a chance to open the chest, so go up to the highest ledge and wait for the lava to go back down before you open the chest. It contains a golden egg.

To open the door in this room, go to the western lava rock and bind to it and pull it away from its current location. This reveals a button. Step on the button when the lava goes away, then go to the northwest corner of the room. Create a lava rock between the northwest platform and the northeast platform, then jump across when the lava goes up, and go through the northeast door.

Go up the ladder and create a lava rock, and bind to it and push it to the right so it's on top of the two lava spouts. Jump onto the lava rock and go to the ledge on the right. Then climb on the rock wall and go to the right. When you're at the right side, create a lava rock to the right, and jump on it. Create an old bed on the right side of the lava rock and jump across to the ledge on the right. Go through the opening on the right.

First, go to the right and go down the ladder.

When the lava goes down, quickly go to the left, create water blocks behind you so you can go back up as soon as the lava starts coming back up, and try to hit the blue switch on the left with an arrow or have a monster echo do it. Then float up in the water blocks before the lava can destroy them.

Then go to the right, and when the lava goes down, make a lava rock over the pit of lava down below and stand on it. You can optionally defeat the torch slug on the rock wall on the right. When the lava goes back up, use the rock wall on the right to go to the right, and go through the opening in the right wall.

Walk in front of the chest and open it to get a Small Key.

Get the Dungeon Map

Go back the way you came until you're in the room with air vents. Go to the left and create a boulder to block the first air vent, then go up the ladder. Approach the rock wall on the right and switch to a statue echo, and hold the Y button to create the statue up against the right wall so it blocks the air vent. Then climb part of the way up the middle of the rock wall and create two statues to the left to block the second air vent. Then carefully climb up when the third air vent stops.

Climb most of the way up the first ladder, then create a boulder just above the ladder. Bind to it and climb the rest of the way up the ladder, then walk to the left with the boulder over your head to block the air vents. Drop the boulder and stand in front of the chest, and open it to get the Dungeon Map.

Find a Second Waypoint

Go to the left and create two statues against the wall to block the air vents, then go down the ladder. If you need to fill your energy gauge, energy keeps appearing in this area, so use it to fill up the energy gauge. Then go to the right and go up the ladder, then go to the right, beware of the Fire Keese, and go up the ladder.

Check on the waypoint to add it to your map.

Dark Bomberman

Unlock the north door and go through.

Catch the bombs that the dark bomberman throws at you, and throw them at the broken blocks around you. Eventually you will reveal more of the climbing wall to the north, as well as some air vents. Climb up and approach the dark bomberman and he will move to a different part of the room. Now he will start sending Bombchus at you. They move in a straight line, even up walls, and explode if they hit you or something breakable.

After you hit him enough times, his tunic turns black. He will throw three bombs or send three Bombchus in a row each time he attacks.

After you hit him more times, there will be a cutscene. Go up and check on the bomb that he left behind, and you will get the Bombs of Might. You can now use bombs by pressing A while in swordfighter form. If you upgrade them at Lueburry's house, you will be able to hold A to charge up the bomb and turn it into a Bombchu.

Go through the door in the northeast part of the room.

Get 100 Rupees

Go to the right and climb up the ladder. You can safely stand on top of the Tweelus. If you stand to the left of the center, the Tweelus will walk to the left. Climb up the ladder on the left.

Energy appears in this area, so collect it to fill your gauge, then go to the right and go up the ladder. Use echoes to create a higher platform on the right to stand on, then switch to swordfighter form and press A to hold a bomb over your head, then try to throw the bomb into the gap in the broken blocks. If this isn't working, you can create a Zirro echo and hold it over your head and face the broken blocks to make the Zirro spit bombs at the broken blocks.

After the broken blocks are gone, use echoes to go to the right side. Defeat the Fire Keese and Tweelus, then go to the right and go up the ladder.

Defeat the Tweelus, then bomb the broken rocks here to find a chest in the northwest corner, which contains 100 rupees, and to reveal the door in the northeast part of the room. Go through.

Fire Wizzrobe

You can use a monster echo such as a Fire Keese to defeat the Fire Wizzrobe, or switch to swordfighter form to fight it.

Get a Third Small Key

Afterward, open the chest to get a small key.

Get a Fourth Small Key

Go south to the previous room, then go down the ladder.

Go down the ladder and go to the left until you reach the dark membrane. If you are out of swordfighter energy, you will find some floating nearby. You can go down the ladder near the membrane to look for more energy. After you have partially (or fully) filled the swordfighter gauge, switch to swordfighter form and hit the dark membrane until it's gone.

Pick up more energy if desired, then go to the left, and you can either switch to swordfighter mode and use bombs to destroy the broken blocks, or you can just use monster echoes such as Bombfish or Zirro to create bombs to destroy the blocks. Behind the blocks, you find a chest. Stand in front of the chest and open it to get a Small Key.

Get the Big Key

Go up the ladder and jump over the gap to the left, and go down the first ladder that you find. Go to the left and unlock the door, then go down the ladder beyond. You reach another room. Go down the ladder in this room.

For a quick way down to the bottom of this room, go to the left and fall off the edge, then go to the right and fall off the edge. From there, go to the left, defeat the Mini-Moldorm on the rock wall if you wish, then climb down the rock wall. Climb east on the rock wall to reach the chest. Go in front of the chest and open it to get the Big Key.

Escape

After you get the Big Key, the lava level in this room will start to rise. Climb up and left on the rock wall. When you get to the top of the rock wall, go to the right and climb up the ladders, but the third ladder will collapse before you can climb up. Create a Strandtula echo where the ladder was, and climb up the strand. Then go to the left and climb up the ladder.

Go north up the slope. The lava will stop.

Go to the Big Door

From the room where the lava stopped, go through the door in the northeast part of the room.

Go up the ladder, and go up the next ladder. Gather energy from this area, then you can either switch to swordfighter form and throw bombs at the broken blocks, or you can use a Zirro echo to create bombs. You'll need to lift a bomb over your head to break the last block. The Bombfish explosion isn't big enough to hit the last block even if you hold it over your head.

Climb up the ladder, unlock the door, and climb up the next ladder.

Create a flying monster echo and pick it up and stand in the air vent to float up. Glide north to the next air vent, but watch out for the lava spouts along the way. Go northeast to the island and throw the pot to get a fairy. Then create a lava rock on the big lava spout near the north part of the ledge. Jump on it to reach the west ledge.

From there, float north from one air vent to another while dodging the fireballs from the Fire Octoroks, and as you go north, dodge the two Fire Keese. Keep floating in the air vents until you can safely go north past the lava spouts. Then let go of your flying monster echo and check on the waypoint to add it to your map. Then unlock the Big Door and go through. Fall into the hole. After a cutscene, you will battle Volvagia.
